Ghetsis is at N's castle after you beat N
After that, he is nowhere!
At the white forest. You can only find him in pokemon white.(I think);)
I think he died
you go to the Pokemon centre near the Pokemon league and there will be a team plasma member there click him and he teleports you to the castle where you have a rematch with ghetis
He gets Taken away and that's that
After you beat the Elite Four, N, and Ghetis, Looker will be in your house.
look on youtube because this place dosent now anything!
Simple answer no. I would advise leaving to train in Nimbasa if you really struggling.
Ghetis
In pokemon white, unlike other pokemon games(well, except for pokemon black), doesn't give you a rod until the end of the game where you already beat N and ghetis and team plasma and other trainers in the game. Oh, you will ONLY receive one rod....which is the super rod!
You can only get reshirem in Pokemon black not white. Its after you beat the Pokemon league for the first time. When you get to the champion team plasma boss will be there with the champion. Then you just follow the story line until you see the leader summon reshirem and your dark orb glows and transforms into zekrom. Then you catch it then fight him
In black two, he will have zekrom, Ghetis will have Kyreum in both.
Dreamworld is a place where you can catch a Musharna every Friday Night. This is also where one of the Ghetis can be found.
